We are putting in an orchard over the next few months. It is going to be approx 70x100. Various fruit trees, grapes and a seperate berry patch in the end. I am thinking of allowing the ducks run of the orchard. I currently have 4 but am really wanting to hatch some ASAP. Will they destroy the orchard? Drill holes are not a big concern. I do plan to seperate the berries from the area the ducks are. They would have their swimming pool and I irrigate 3 days per week. Will eventually add a pond either this year or next.
